💡 Hint

Common Mistakes

Choosing a device that is not typically an embedded system like Desktop.

The device name is set to "Smartphone" because it is a common embedded system device.

2fill in blank

medium

Complete the code to check if a device is an embedded system.

Intro to Computing

if device_type == "[1]":
    print("This is an embedded system.")

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Choosing general-purpose computers instead of embedded devices.

Microwave ovens contain embedded systems controlling cooking functions.

3fill in blank

hard

Fix the error in the code that simulates an embedded system sensor reading.

Intro to Computing

import random
sensor_value = [1](10, 100)
print(f"Sensor reading: {sensor_value}")

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using randint without the random module prefix.

Using random.range which does not exist.

The correct function to get a random integer between 10 and 100 is random.randint.

4fill in blank

hard

Fill both blanks to create a dictionary of embedded devices and their functions.

Intro to Computing

embedded_devices = {"[1]": "controls temperature", "[2]": "manages lighting"}

Drag options to blanks, or click blank then click option'

BSmartphone

CSmart Bulb

💡 Hint

Common Mistakes

Using general-purpose devices like Laptop or Smartphone which are not specific embedded devices here.

Thermostat controls temperature and Smart Bulb manages lighting, both are embedded devices.

5fill in blank

hard

Fill all three blanks to create a list comprehension of embedded system devices with their power status.

Intro to Computing

device_status = [{"device": [1], "power": [2] for [3] in devices]

Drag options to blanks, or click blank then click option'

A"Smartwatch"

B"On"

Cdevice

D"Off"

💡 Hint

Common Mistakes

Not using quotes for strings, or using incorrect variable names for iteration.

The list comprehension creates dictionaries with device name from the variable device, power status "On", iterating over variable device.
